Irabha izoshintsha ukwakheka kwayo okuqinile uma kusetshenziswa amandla angama-Newton angu-6 kuya kwangu-8 kuyo. Uma amandla angaphezu kwama-Newton angu-8, irabha izophuka.

Impendulo efanele ngu-E.

Ukunwebeka okungaguquki

22. Qaphela idatha yokuhlola yezinhlobo ezinhlanu zamathayi enjoloba u-A, u-B, u-C, u-D no-E adonswa ngamandla u-F ukuze ubude bawo bukhule. Ithayi lenjoloba eline-spring constant encane kakhulu…

Ifomula yomthetho kaHooke :
k = F / Δx
Incazelo: k = ukungaguquguquki kokuguquguquka, F = gaya, Δx = ukwanda kobude berabha
Ukungaguquguquki kwerabha:
k_A = F / Δx = 1 / 0,05 = 20 N/m
k_B = F / Δx = 2 / 0,025 = 80 N/m
k_C = F / Δx = 1 / 0,025 = 40 N/m
k_D = F / Δx = 2 / 0,05 = 40 N/m
k_E = F / Δx = 2 / 0,25 = 8 N/m
Impendulo efanele ngu-E.

23. Kusukela ekuhlolweni ukuze kutholakale ukunwebeka kwerabha kusetshenziswa irabha yethayi, idatha etholiwe injengoba ikulethebula elilandelayo. Kungaphethwa ngokuthi inani elingaguquki elikhulu kakhulu ukuhlolwa….

Ifomula yomthetho kaHooke:
k = F / Δx
I-constant yasentwasahlobo:
k_A = 7/0,035 = 200 Nm^-1
k_B = 8/0,025 = 320 Nm^-1
k_C = 6/0,020 = 300 Nm^-1
k_D = 9/0,045 = 200 Nm^-1
k_E = 10/0,033 = 303 Nm^-1
I-constant enkulu kunazo zonke enwebekayo yi-320 Nm^-1.
Impendulo efanele ingu-B.
